File with guid as filename is not served.

I am using fonts from fonts.com that are named with a guid.

"080c59ed-2c7d-48e2-8d35-73da0b57a6c3.woff".

The fonts are not served do to how Sprockets::Server.path_fingerprint works.

I am including a test that triggers my problem and also a fix for it. All tests pass.
